-cari dulu mol bagi dua solution
-compare kan nanti dapat tahu mana satu yang excess
-pakai formula heat kat atas ni
-per kan dengan 1000 (kat soalan tu dia kJ)]]> 2021-10-01 05:14:15 UTC https://padlet.com/m4316066/nzgh643swplg6cor/wish/1783372172 m6095891 https://padlet.com/m4316066/nzgh643swplg6cor/wish/1783374220 Thermochemistry
- endothermic (absorbs heat), exothermic (releases heat)
- heat of change negative = exothermic, heat of change positive = endothermic (based on graph/product-reactant)
- endothermic reaction includes;
1. SPA salt in H20
2. Sodium hydrogen carbonate + H20
3. Heatingof carbonate in nitrate salt
4. Photosynthesis
- yang lain semua exothermic reactions
- The total energy content in the products is higher than the total energy content in the reactants(endothermic)
-The total energy content in the products is lower than the total energy content in the reactants (exothermic)]]> 2021-10-01 05:15:23 UTC https://padlet.com/m4316066/nzgh643swplg6cor/wish/1783374220 thermochemistry (adelynn) https://padlet.com/m4316066/nzgh643swplg6cor/wish/1783451688 Q = mcθ [Heat energy needed]
ΔH = [Heat released] (-)EXO (+)ENDO
-Kalau macam dia ada percampuran dua solution, m(mass)/volume kena tambah (sebab solution level akan increase)
-exo release heat, endo absord heat
-exo temp increase, endo temp decrease [temp of surrounding] [yang absorb or release tu reactant]
-ENDO (ingat endo sebab dia sikit je)(selain ni semua exo)
🟡 sodium/potassium hydrogen carbonate +H2O/acid
🟡 SPA dissolve in water
🟡 photosynthesis
🟡 carbonate/nitrate salt
-energy of product dengan reactant, bole tengok energy level diagram. ΔH = product - reactant
🟣 EXO = energy reactant > energy product
🟣 ENDO = energy product > energy reactant
-kalau ada dua mol, cari dua dua lepastu compare kan (jangan ambik yang excess nanti lagi satu tu ta cukup) (*ambik paling kecik)
